DRAFT-ARM FOR SODA-FOUNTAINS.

To all whom t may concern: y

Be it known that we, BEATTIE R. WORLEY and'GEonGE H. KELLINGTON,citizens of the United States, residingat Decatur, in the county ofMacon and State of illinois, have invented certain new and usefulImprove-` ments in Draft-Arms for Soda-Fountains; and we do herebydeclare the following to be a full, clear, and exact description of the'invention, such as will enable others ASkilled in the art to which itappertains to make and use the saine.

This invention relates to new anduseful improvements in draft arms forsoda fountains',vand has for its principal obj ect toprovidea devicewhich at all times will remainv arrangement of parts-which will be fullyset forth in the following specification and in the accompanyingdrawing, in which: i

Figure 1 is a view in elevation of a draft vention. l? ig. 2 is atransverse sectional view therethrough, illustrating` the details ofconstruction, and Fig. 3 is' a longitudinal sectional view of the draftarm.

Referring now .to the drawings by char-v acters of reference, thenumeral'l desiimatesv the body of the device, which is preferablycylindrical and is provided wit-hthe internally screw threaded bore 2. Alateral eX- tension 3 is formed on the body,'and is provided with thebore l provided at its upper terminal with the screw' thread '5 withwhich the externally screw threaded ,plug 6 is ar- A suitable plugf is]rangedto coperate. threaded into the bore 2, and this plug has formedcentrally thereof theaXial bore 8 the use of which will appear as thedescription proceeds. A suitable lock nut 9 is arranged to be threadedon plug 2 as illustrated in Fig. 2, and it will thus be seen that theplug 7 will be held against movement. Extending transversely through thebody l is the transverse bore 10 which communicates with the bore 2hereinbefore described. A reduced `Speticat-.on of Letters Patent. l

aXial bore 11 is formed on the side of the transverse'bore opposite theone with which the bore 2 communicates, the use of which will appear lasthe description proceeds.

rllhreaded into the body on its under side, is the nozzle '12 havingformed centrally thereof lthe longitudinal aperture13 which is arrangedto communicate with the laperture l0 to permitthe liquid to owtherethrough. A suitable washer 14 is removably securedfto the end oflthe body opposite the one in which the bore 2 is formed, and thiswasher is held in place by means of the screw 15 which Visfth'readedintothe body as illustrated in Fig. 2. ARotatab'le within the bore 8 inthe plug 7 is the shaft 16 having formed intermediate its" ends the cam17 which is slotted as illustrated'in Figs. 2 and 3, t0 receivethedischarge nozzle Vo f the valve,

which .will be imore fully hereinafter described.

A rubber gasket 18Vis secured .againstlthe bottom wall ofthe bore 4L,,as clearly shown in the drawing, and this gasket is arranged to form aseat for the valve 19 lprovided with the vconical face 20 having at its.apex the enlargement 21. The conical face '20 is arranged to coperatewith the inverted conicalface 22 ofthe plug6 vin forcing'the valvedownwardly while the lnob or enlargement 21 limitsjthe upward movementof thevalve.

It wi'ljl 'be noted .that the inclination zof the conical'ibase `204will serve so that when'the liquid impinges thereon the valve will begradually `forced to its seat landthe liquid will be ,dashed upwardlyagainst the vinclined face of the inverted conical lportion 22 of theplate 6 against which it impinges and vis directed 'against the inclinedface 20 Vof the valve. In thisway it will be seen that the valve willbeforced to its seat.

'f Formed vcentrally of the under side of `the valve 19 is'y'the tubularextension 23 which terminates at its lower terminal in the re'- duced.tubular extension` .2.4:vv which projects between the sections of thecam 17 as shown 'in the drawings. A plurality of transverse bores 25 areformed in the tubular member 23 at a point slightly below the lower faceof the valve 19, and these apertures are arranged to form. outletopenings which will permit the water to flow through the aper-v ture 26in the body into the nozzle 12 as clearly shown in the drawings.A Asuitable collar 27 is formed on the body and is'interrnally screwthreaded as at 28, and this collar is arranged to form the yconnectionbetween the water supply and the faucet. The liquid is supplied to thefaucet through the pipe 29 and it will beapparent that when the valve isin its closed position pressure will be exerted on the upper facethereof and hold the same closed.

A rectangular extension 30 is formed on the outer end of the shaft 16and this extension is arranged to project through the rectangularaperture 31 formed in the arm 32 of the U-shaped lever designatedgenerally by the numeral 33, the opposite arm of the Lil-shaped lever ispivotally secured to the washer by means of the bolt l5 as clearly shownin Fig. 2. A suitable knob or handle 3a is secured to the Ybight portionl of the U-shaped lever, and this knob is arranged to form a handhold bymeans of which the device is controlled.

lt will be apparent from the foregoing, that in use the device isconnected to the water supply in the usual way, and upon operation ofthe lever 33,'it will'be appa-rent that the shaft i6 will be rotated,which, in

turn will rotate the cam 17 and thereby lift the valve 19 from its seat.rhis will cause the same to pass upwardly beyond the opening 26 and theliquid will then flow beneath the valve and through the aperture 25 intothe nozzle Q4, from whence it will flow into the delivery nozzle l2.Upon releasing the handle, it will be apparent, that Vthe liquidpressure against the surface 20 of the valve 19 will force the samedownwardly against the seat, and thereby shut o' the supply. ft

vwill thus be seen, that an automatic means within the scope of theclaims may be re-y sorted to without departing from the spirit and scopeof the invention.

Having thus described the invention, what is claimed as new, is

1. A, draft arm for soda fountains in cluding a cylindrical body, saidbody having a transverse aperture therethrough and being provided with alongitudinal bore communicating with the aperture, an angular extensionon the body, said angular extension being provided with an enlarged borecommunicating with the transverse aperture, a cam operatively mountedwithin the longitudinal bore in the body, a valve slidable in the borein the angular extension, the upper wall of the valve beingconical, atubular nozzle secured to the valve and arranged to direct the fio-w ofthe liquid when the valveis open, the cylindrical extension beingprovided with an inlet opening, said inlet opening being located at apoint slightly above the valve when the same is seated and meanscontrolling the operation of the cam whereby the valve is controlled.

2. A draft'arm for soda fountains including a cylindrical body, saidcylindrical body being provided with an axial bore and having atransverse bore communicating with the axial bore, a cylindricalextension on the body, saidextension projecting laterally therefrom andbeing provided with an enlarged bore, the lower terminal of the enlargedbore communicating with the transverse bore in the body, a valveslidable in the bore in the cylindrical extension, means within thetransverse bore in the body controlling the operation of the valve, anda discharge nozzle formed integral with the valve andprojectingdownwardly therefrom, said discharge nozzle projecting intothe axial bore in the body, the cylindrical extension being providedwith an inlet opening at a point slightly above the valve seat, saidinlet opening being so positioned that the pressure of the liquid willhold the valve closed.

In testimony whereof we affix our signatures in presence of twowitnesses.
